A method for providing a liquid display displaying a selectable pattern where either light rays are characterized by at least one light parameter, and light deflecting means depend on the light parameter, or the light deflecting means are characterized by at least one deflecting parameter and the light rays depend on the deflecting parameter.

A low profile, lighted waterfall apparatus for producing a sufficiently lit artificial waterfall having a light source chamber, distal to a waterfall slot/primary outlet and substantially aligned on the same plane therewith, and a port for accessing the light source, such that the light source can be easily accessed, inserted, removed, and/or replaced. The light source chamber having a transparent, semi-transparent, or translucent divider to shine light towards and across the waterfall slot/primary opening via a grooved spreading manifold/area/passage. The grooved spreading manifold/area/passage configured to spread the flowing water, and direct the water as a fluid wave guide towards the waterfall slot/primary outlet.

An outlet device with hollow water curtain function includes a hollow housing and a deflecting column inserted in the housing. An annular passage is formed between the housing and the deflecting column. The housing further includes a plurality of arc-shaped inlet slots. The arc inlet slots are annularly arranged about the center of the annular passage. The internal port of the arc inlet slots is connected to the annular passage. Water flows to the annular passage through the arc inlet slots to from a hollow annular water curtain with centrifugal force. When the tangential centrifugal force of the water curtain orienting the opening angle of the housing is larger than the surface tension thereof, the water curtain breaks open to make the water flowing break open and diffuse as particles after keeping itself in a certain length. The diffused water forms a water type continuous in a certain range.

A waterfall apparatus for viscous food products including a collection bowl. An auger tube extends perpendicular to the bottom surface of the collection bowl. Inside the auger tube is an auger having a spiral flight protruding along the length of the auger. The auger is coupled to a motor which operates to rotate the auger. The spiral flight supports a viscous food product such as melted chocolate received from the collection bowl as the auger rotates, moving the melted chocolate upwardly from the collection bowl to the top end of the auger tube onto a spillway at the top of the waterfall apparatus. The melted chocolate flows from the top end of the auger tube onto the spillway and flows downwardly to the collection bowl, coating one side of one or more removable decorative pattern plate. The spillway is configured to ensure an even flow of chocolate over the entire width of the removable decorative pattern plate.

A fountain is provided. The fountain includes: a drape; a catch basin located below the drape and oriented to catch a fluid flowing at least one of over and through the drape; a conduit fluidly connected to the catch basin forming a circuit to return the fluid in the catch basin to flow at least one of over and through the drape; a pump fluidly connected to the circuit and configured to pump the fluid through the conduit; and at least one of the drape, catch basin, conduit includes surface oriented to contact the fluid and the surface includes at least one of copper and silver.

A water jet device for recreational purposes, in particular a fountain, having: a jet head with at least one water infeed opening and at least one set of water outlet nozzles, the nozzles being arranged in a same plane and on a peripheral line of the jet head, the nozzles including respective outlets oriented towards the outside of the jet head, a water flow regulator supplying the nozzles to produce a water velocity defining a water jet, exiting each nozzle, having a selected substantially parabolic-shaped path, the water jets exiting the nozzles forming at least one dome portion, and at least one water supply column made of a rigid material and including an inlet connected to a water infeed and a water outlet connected to the opening of the jet head and mechanically integral thereto, the supply column having the selected parabolic shape to blend with the dome portion.

A showerhead includes a water outlet and a deflector in axial spaced relation to the water outlet. Water discharged from the water outlet is configured to extend axially through a vertical opening and impact the deflector to form a sheet-like water layer.

A water nozzle with a flow head is provided with at least two separate water supply devices that supply, in a controllable fashion, different water volume flows to the flow head. The flow head generates an annular jet from the different water volume flows. By controlling the water volume flows, alternatively a slim annular jet or a widened annular jet is generated by the flow head. A deflection element with a central outlet opening is provided, wherein the central outlet opening is arranged in a flow direction of the annular jet downstream of and spaced apart from the flow head. A deflection device surrounds the central outlet opening. A diameter of the central outlet opening is designed such that the slim annular jet is able to pass through the central outlet opening while the widened annular jet impacts on the deflection device surrounding the central outlet opening.

Systems and apparatus for a water fountain that converts turbulent flow of a fluid to laminar flow. The water fountain may include a basin, a fluid distribution port, at least one water support, a fluid distribution media, and an annular scupper. The fluid distribution port may be located within the basin above the bottom and between the circular inner wall and the outer wall. The at least one water supply port may extend through the bottom and coupled to the fluid distribution port. The fluid distribution media may be located within the basin, between the circular inner wall and the outer wall, and above the fluid distribution port. The annular scupper may be located on top of the inner wall and capable of applying a surface tension to a fluid to thin the fluid into a continuous laminar sheet downward in a circular cascade sheet into a cascade chamber.

Nozzle orifice shapes and configurations associated with regulating and directing a flowing body of water over a water attraction riding surface for performing board-riding maneuvers is described. The nozzle orifice shapes and configurations according to the present invention includes shapes and configurations allowing for a flow of water over a ride surface which may include complex shapes which do not lend themselves to use with existing nozzle technologies. The present invention also includes nozzle arrays which may be made up of two or more nozzles arranged substantially adjacent or within close proximity to one another to create beneficial flow characteristics for performing board riding maneuvers on a complexly shaped riding surface.
